Guinean Forests Of West Africa
The Guinean forests of West Africa is a biodiversity hotspot designated by Conservation International, which includes the belt of tropical moist broadleaf forests along the coast of West Africa, running from Sierra Leone and Guinea in the west to the Sanaga River of Cameroon in the east. The Dahomey Gap, a region of savanna and dry forest in Togo and Benin, divides the Guinean forests into the Upper Guinean forests and Lower Guinean forests. The Upper Guinean forests extend from Sierra Leone and Guinea in the west through Liberia, Côte d'Ivoire, and Ghana to Togo in the east. The Lower Guinean forests extend east from Benin through Nigeria and Cameroon. The Lower Guinean forests also extend south past the Sanaga River, the southern boundary of the hotspot, into southern Cameroon, Equatorial Guinea, Gabon, Republic of the Congo, Cabinda, and Democratic Republic of the Congo. Ecoregions The World Wide Fund for Nature divides the Upper and Lower Guinean forests into a number of di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biodiversity Hotspot
A biodiversity hotspot is a biogeographic region with significant levels of biodiversity that is threatened by human habitation. Norman Myers wrote about the concept in two articles in ''The Environmentalist'' in 1988 and 1990, after which the concept was revised following thorough analysis by Myers and others into “Hotspots: Earth’s Biologically Richest and Most Endangered Terrestrial Ecoregions” and a paper published in the journal ''Nature'', both in 2000. To qualify as a biodiversity hotspot on Myers' 2000 edition of the hotspot map, a region must meet two strict criteria: it must contain at least 1,500 species of vascular plants (more than 0.5% of the world's total) as endemics, and it has to have lost at least 70% of its primary vegetation. Globally, 36 zones qualify under this definition. These sites support nearly 60% of the world's plant, bird, mammal, reptile, and amphibian species, with a high share of those species as endemics. Some of these hotspots support up ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gabon
Gabon (; ; snq, Ngabu), officially the Gabonese Republic (french: République gabonaise), is a country on the west coast of Central Africa. Located on the equator, it is bordered by Equatorial Guinea to the northwest, Cameroon to the north, the Republic of the Congo on the east and south, and the Gulf of Guinea to the west. It has an area of nearly and its population is estimated at million people. There are coastal plains, mountains (the Cristal Mountains and the Chaillu Massif in the centre), and a savanna in the east. Since its independence from France in 1960, the sovereign state of Gabon has had three presidents. In the 1990s, it introduced a multi-party system and a democratic constitution that aimed for a more transparent electoral process and reformed some governmental institutions. With petroleum and foreign private investment, it has the fourth highest HDI in the region (after Mauritius, Seychelles and South Africa) and the fifth highest GDP per capita (PPP) i ...

Cameroonian Highlands Forests
The Cameroonian Highlands forests, also known as the Cameroon Highlands forests, are a montane tropical moist broadleaf forest ecoregion located on the range of mountains that runs inland from the Gulf of Guinea and forms the border between Cameroon and Nigeria. This is an area of forest and grassland which has become more populous as land is cleared for agriculture. Geography The Cameroonian Highlands forests extend across the Cameroon Highlands, a chain of extinct volcanoes, covering an area of in eastern Nigeria and western Cameroon. The highlands extend roughly southwest–northeast. In the southwest the ecoregion includes the Rumpi Hills, Bakossi Mountains, Mount Nlonako, Mount Kupe, and Mount Manengouba. It extends northeast towards the Mambila Plateau, and north to the Bamenda Highlands. It continues northeast along the western flank of the Adamawa Plateau to Tchabal Gangdaba. Northern outliers include the Mambilla Plateau to the northeast, Nigeria's Obudu Plateau to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Niger Delta Swamp Forests
The Niger Delta swamp forests is a tropical moist forest ecoregion in southern Nigeria. It consists of freshwater swamp forests in the Niger Delta of the Niger River. This swamp forest is the second largest in Africa, after the Congolian swamp forests. Although there are large cities just outside the ecoregion, the area has been relatively isolated by the difficulty of building roads across the swamps, although this is changing with development of oil and logging industries. Scientific surveys have only begun in recent years, and new species were being identified into the 1990s. Location and description The Niger Delta swamp forests ecoregion covers a triangular territory at the mouth of the Niger River. The southern edge is set back about 10 km from the Gulf of Guinea, buffered by the Central African mangroves ecoregion where the effects of salt water are more pronounced. The western border of the ecoregion is formed along the Benin River, the northern tip is just north of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nigerian Lowland Forests
The Nigerian lowland forests is a tropical moist forest ecoregion in southwestern Nigeria and southeastern Benin. The ecoregion is densely populated, and home to several large cities including Lagos, Ibadan, and Benin City. There is still significant tree cover, but the remaining enclaves of forest are increasingly fragmented. The ecoregion is wetter along the coast and drier inland, resulting in bands of vegetation zones that run parallel to the coast for the 400 km length of the region. Geography The Nigerian lowland forests are bounded on the south by coastal mangroves and the Gulf of Guinea, on the east by the Niger River and its delta, on the north by the Guinean forest-savanna mosaic. On the west it is bounded by the Dahomey Gap, a drier coastal region where forest-savanna mosaic extends all the way to the ocean, separating the Lower Guinean forests, of which the Nigerian lowland forests are part, from the Upper Guinean forests of West Africa."Nigerian lowland forests".

Eastern Guinean Forests
The Eastern Guinean forests are a tropical moist broadleaf forest ecoregion of West Africa. Geography The ecoregion includes the lowland forests extending from the Gulf of Guinea a few hundred kilometres inland, from western Côte d'Ivoire to the western shore of Lake Volta in Ghana. A few enclaves lie further east and inland in the Togo Mountains of Togo, eastern Ghana, and Benin. The Sassandra River of Cote d'Ivoire separates the Eastern Guinean forests from the Western Guinean forests which lie to the west. Inland and to the east, the Eastern Guinean forests transition to the Guinean forest-savanna mosaic.Burgess, Neil, Jennifer D’Amico Hales, Emma Underwood (2004). ''Terrestrial Ecoregions of Africa and Madagascar: A Conservation Assessment''. Island Press, Washington DC. Cities in the ecoregion include Abidjan and Yamoussoukro in Ivory Coast and Kumasi in Ghana. The Eastern Guinean forests, together with the other tropical moist broadleaf forests of West Africa, is i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guinean Montane Forests
The Guinean montane forests are a tropical moist broadleaf forest ecoregion of West Africa. The ecoregion occupies the portions of the Guinea Highlands lying above 600 meters elevation, extending across portions of Guinea, Sierra Leone, Liberia, and Côte d'Ivoire. It includes the Fouta Djallon plateau and the massifs of Ziama, Simandou, Tétini, Béro, Kourandou in Guinea, the Loma Mountains and Tingi Hills in Sierra Leone, the Nimba Range in Guinea, Liberia, and Côte d'Ivoire, and the Monts du Toura in Côte d'Ivoire. Mount Bintumani in the Loma Mountains is the highest peak in West Africa west of Mount Cameroon. The next highest peaks in the region are in the Sankan Biriwa massif (1850 meters) in the Tingi Hills. Average rainfall is between 1,600–2400 mm per year and many important rivers have their sources in these mountains. Flora These mountains have a distinct plant cover in various phases according to elevation, with up to 35 endemic species including a '' R ...

Ecoregion
An ecoregion (ecological region) or ecozone (ecological zone) is an ecologically and geographically defined area that is smaller than a bioregion, which in turn is smaller than a biogeographic realm. Ecoregions cover relatively large areas of land or water, and contain characteristic, geographically distinct assemblages of natural communities and species. The biodiversity of flora, fauna and ecosystems that characterise an ecoregion tends to be distinct from that of other ecoregions. In theory, biodiversity or conservation ecoregions are relatively large areas of land or water where the probability of encountering different species and communities at any given point remains relatively constant, within an acceptable range of variation (largely undefined at this point). Three caveats are appropriate for all bio-geographic mapping approaches. Firstly, no single bio-geographic framework is optimal for all taxa. Ecoregions reflect the best compromise for as many taxa as possible. Se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
